  • Air jet piddling
    Patent number: 6131785
    Abstract: An aspirating jet piddler that has no moving parts and operates to achieve a soft laydown with reduced tangling.
    Type: Grant
    Filed: August 27, 1998
    Date of Patent: October 17, 2000
    Assignee: E. I. du Pont de Nemours and Company
    Inventors: Frank William Anderson, James Victor Hartzog, Darren Scott Quinn
  • Sheath-core polyester fiber including an antimicrobial agent
    Patent number: 6037057
    Abstract: A sheath-core polyester fiber where the sheath includes an antimicrobial agent and the sheath comprises less than thirty percent of the total cross-sectional area of the fiber. The antimicrobial agent is selected such that the relative viscosity of the fiber lies above a defined spinnability limit, so that spinning is possible. With no loss in antimicrobial efficacy, the fiber of the present invention may be slickened with a siliconized finish in order to reduce fiber friction, thus giving the fiber a silky feel.
    Type: Grant
    Filed: February 13, 1998

    Assignee: E. I. du Pont de Nemours and Company
    Inventors: James Victor Hartzog, Darren Scott Quinn
  • Air jet piddling
    Patent number: 6032844
    Abstract: An aspirating jet piddler that has no moving parts and operates by swirling a textile tow line pneumatically to achieve a soft laydown with reduced tangling.
    Type: Grant
    Filed: July 31, 1997
    Date of Patent: March 7, 2000
    Assignee: E. I. du Pont de Nemours and Company
    Inventors: James Victor Hartzog, Darren Scott Quinn

  • Bicomponent polyester fibers
    Patent number: 5723215
    Abstract: Bicomponent polyester fibers that have "spiral crimp" on account of a difference in chain-branched content of the polyester polymers of the components. Such bicomponent fibers are preferably hollow and may be slickened, such as for use as filling material for pillows or other filled articles.
    Type: Grant
    Filed: February 3, 1997
    Date of Patent: March 3, 1998
    Assignee: E. I. du Pont de Nemours and Company
